 * Hi,
 * My hosting has a few php functions disabled, so recently I have been getting 
   these errors in the logs. Did not check the code where it is used exactly, but
   is there a way to add a check whether the function is enabled or not?
 * Thanks in advance!

 * Hey Peter, I think this is fixed in version 4.3.5. Let me know if it fixes it
   for you and if not please click the ‘Send debug log to developer’ button on the
   plugin’s settings page.
 * thanks
